DreamScape: Browser-Based 3D World Builder Powered by Claude Code and MCP
What DreamScape Does
DreamScape is a browser-based 3D world builder powered entirely by Claude Code through the Model Context Protocol (MCP). Users describe what they want in natural language (e.g., "add a castle on that hilltop," "spawn a dragon and make it fly around") and Claude builds it while they're standing in the scene.
Technical Implementation
The system uses Claude Code to control 30 MCP tools that handle:
- Terrain generation
- Procedural model creation via Blender
- Lighting and weather systems
- Physics and animations
- Scripting and component management
- Asset uploads
Key MCP Integration Features
From a Claude/MCP perspective, several technical details stand out:
- Claude sees the full scene graph and spatial layout before placing anything
- It can attach PlayCanvas scripts to entities for behaviors like patrol paths, physics interactions, and particle effects
- The
dreamscape_evaltool lets Claude execute arbitrary JavaScript in the 3D runtime and read results back dreamscape_validate_placementchecks ground contact via raycast before placing objects- Claude handles entity metadata, component management, and asset uploads through discrete MCP tools
Collaboration and Interaction
The platform includes voice chat integration where users can speak to Claude in the scene and receive TTS responses. Multiple people can join the same session and watch Claude build in real time. The source mentions an active multiplayer session featuring a boss fight with a weaponed dragon.
The tool is currently free with no signup wall. The developers are seeking feedback on how Claude handles spatial reasoning and multi-step scene construction, particularly from those experimenting with MCP tool use.
